72 THE FOSSIL CORALS AND 



pali are upon the septa where they join. The rest of the septa of this system are long 

 and slender, and one is placed between each pair of those last mentioned. The calice is 

 thus made up of a number of sets of eight septa. The sides of the septa are largely 

 and distinctly granular. The costse are large, unequal, largely granular in a single row 

 on the outside, and granular and multigranular on the sides. The single row of 

 granules becomes very distinct between the epithecal bands. 



The breadth of the base of several specimens is from -j^ to 1 inch and 1-^ inch, and 

 the height is from -^ inch, -^ inch, to 2 inches.

Tegchoctathus Naeiensis, Duncan. Variety. Plate XVI, Figs. 9, 10. 



A variety of this polymorphic species requires notice, as the junction of the septa 

 and the presence of the pali within it are not always seen. The large or primary septa 

 of the five cycles have no pali ; the next have them, and so have the next to them in 

 size. A columella is visible. 



Locality. Near Eaduk, Nari group. Survey-number G -7^.

There is a rather conical-shaped corallum of this widely distributed Eocene coral in 

 the Nari series, west of Bhagathoro Hill, south of Sehwan. It has a widely open calice 

 whose surface is flat, with a small axial space. The epitheca is pretty strong, and the 

 costse are more or less distinct to the base. The pali are very evident. Faint exothecal
